Im level 12, a somewhat pure sword and board warrior.
I leave whiterun after turning saddia in and go around the city and find some smugglers, no big deal, tough fight but win.
Then three more come in, one of which is a caster. In two spells I die. TWO SPELLS.
I know I dont have any magic resistance or lightning resistance but COME ON. Two spells?!?
Even if I equipped my newly gotten fast healing it wouldnt do much, and this mage with his dagger BLOCKED my shield bash twice.
Good job breaking your own game bethesda, Ill go play something else till you figure out you needed the Creation Kit and modders sooner to FINISH YOUR GAME.
By any chance did you get the Patch which came out last week? Because that broke all magical defences, mate. There's supposed to be another patch out this week to fix it, but it makes getting hit by spells VERY effective.
Works botth ways, of course. You can trounce AI units in the same way, but as a pure Warrior, it svcks. You cannot defend yourself adequately against mages without magical armour. And a mage with Fireball can do HEAVY damage as it is.
Wait for the next patch. It'll make things a LOT more balanced again.
